Beatlemania was the fanaticism surrounding the English rock band the Beatles from 1963 to 1966. The group's popularity grew in the United Kingdom in late 1963, propelled by the singles "Please Please Me", "From Me to You" and "She Loves You". By October, the British press adopted the term "Beatlemania" to describe the scenes of adulation that attended the band's concert performances. By 22 February 1964, the Beatles held both the number one and number two spots on the Billboard Hot 100, with "I Want to Hold Your Hand" and "She Loves You", respectively. Their world tours were characterised by the same levels of hysteria and high-pitched screaming by female fans, both at concerts and during the group's travels between venues. Commentators likened the intensity of this adulation to a religious fervour and to a female masturbation fantasy. Among the displays of deity-like worship, fans would approach the band in the belief that they possessed supernatural healing powers.

The Beatles were an English rock band formed in Liverpool in 1960, comprising John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band of all time and were integral to the development of 1960s counterculture and the recognition of popular music as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways. The band also explored music styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionized many aspects of the music industry and were often publicized as leaders of the era's youth and sociocultural movements.
